Quicktime TVBR vs Nero AAC

Well, the best way to answer that question would be for you to conduct your own series of blind ABX tests. What works for one person doesn't necessarily work for another. We don't have your music, equipment, listening environment, tastes, or ears.

Quicktime TVBR vs Nero AAC

In my opinion Quick Time and nero has about the same quality, but QT has a little more flexible VBR mode, so in some cases it can give a little higher quality. But at the same time QT has such problems like limiting of signals with high level (close to 0dbFS) which results in dynamic range compression.

You're saying there's a commandline encoder for QuickTime I can just download? Because I'm using Ubuntu Maverick with WINE and foobar2000 to do the volume normalizations and converting with NeroAACEnc. For some reason LAME wouldn't work with WINE it kept giving me demands for various extra files, doesn't matter since AAC is superior anyway.

I also find Quicktime to be a lot better than Nero around 128kbps. It's easy to hear when you compare so that's why I haven't done an ABX.

ABX tests are needed, it doesn't matter how "easy" you think it is to hear as you could very well be suffering from the placebo affect. Proper testing is required before anyone makes subjective audio claims, period. That is in the TOS (specifically TOS #8) that everyone agrees upon when joining the site. So proper test results are needed from both you and list before any audio quality claims can be taken seriously. That and the Nero devs would like to know the performance of their encoder and just what samples their encoder is having issues with. That way they can fine tune their encoder so that Apple's is not "much better" and comparing the two won't be so "easy to hear."

kc2002 just explained that any claim of difference in quality is worth nothing until evidenced by a blind test. Otherwise, expecting to hear differences can cause the listener to hear them where they don't exist.

expecting to hear differences lead you to hear them where they don't exist.

No, i was not expecting to hear any difference. Once i disided to include the qt aac in my gui and make some simple tests using it for video series, and i surprised when i saw the difference at first sight. So i decided to try also with some of my music.. and i said: woow there is a difference. Easy to hear at 128kbps.Im not audio tester, i only noticed a difference and decided to share it here. (i thought people know that difference) so was i wrong?

You're missing the point. When you were comparing the two codecs, did you know which was which? If so, your claim is not objective. Claims of audible differences in sound quality are of no use unless they are backed up by objective evidence gathered in a blind listening test. Subjective claims are proscribed by this site's rules, which users must (at least tacitly) agree to while creating an account.

I can assure you that any difference you think you heard was not there as you don't have my equipment. Only proper audio quality judging can be used on my system with my Denon AKDL1 Dedicated Link Cable ($1,000), pair of AudioQuest K2 terminated speaker cables ($17,000), properly broken in tube amp ($23,000), 48" quad speakers with 45 lb magnetic drivers ($46,700), and Ailenware desktop with external sound card ($7,600) running the Microsoft Zune PC software. I say: Wow, there is a huge difference in listening to audio with what you have and my system is a million bagillion times better than yours. It is so easy to hear that blind testing isn't required.

See why proper testing is needed before any audio quality claims are made? It doesn't matter if the difference is "easy to hear." You need proper testing to backup your claims, period. Don't like it? Well, those are the rules here which you and everyone else agreed upon. There is a reason why that is part of the rules and it is enforced here.

After all, encoders will be used by 99% normal users with a normal hardware, right?So, if you can't notice the difference with a high-end equipment, but other does with a simple hardware encoding a not simple movie. Is that important?

I really don't understand what you are saying or the point you are trying to get across. There are rules in place that need to be followed, it doesn't matter what anyone else says. They are a fundamental part of this site and you can either follow them or not participate in the forums. You obviously aren't understanding the need for proper testing in order to backup or refute subjective claims.
